Running dash on AWS hosted on site, freezes when too many browsers open


I am currently running my dashboard on an aws server. This dashboard can be viewed by anyone with access. It seems whenever there are 4 browsers open, the webpage no longer updates, but looking at the output file of the dash application, the callbacks are still being triggered and should be ‘posted’. My theory is that currently the cpu usage of all scripts running on the server is too high, and so is effecting update of the webpage. Any ideas, I am not using Gunicorn as I don’t understand exactly what it is used for.
